What is the concentration of a solute, in g/100 cubic centimaters, if one can dissolve 5.0g of the solute in 20.0 cubic centimeters of solvent?

What is the concentration of a solute, in g/100 cubic centimeters, if one can dissolve 5.0g of the solute in 20.0 cubic centimeters of solvent?


Simple proportion:

\frac {5.0\,g}{20\,cm^3} = \frac {x}{100\,cm^3}

Can you figure it out from there?

There's only the math to do in your question...

Your question itself show what to do; see:


What is the concentration of a solute, in g/100 cubic centimaters

So, you can have your formula;

Concentration = \frac{mass(g)}{volume(100cm^3)}

Now, in 20 cm^3, you have 5.0 g

How many grams would there be in 100 cm^3? This is simple proportions.

Hope it helped! :)
